Without ANA Test or Skin Biopsy for DLE in Ears with Urine and Complete Blood being Normal, could SLE be found at this point without ANA and Biopsy?

No. If someone told me about discoid lupus confined to the ears, I would wonder whether this isn't really seborrheic dermatitis. Systemic lupus is diagnosed on clinical criteria. What you have shared doesn't even approach what you need. I hope this helps.
